An effective acid pretreatment of agricultural biomass residues for the production of second-generation bioethanol

“…The physical and chemical pretreatments performed on beet and date materials were required to reduce recalcitrance biomass for hydrolyzing complex sugars (mainly sucrose) into simple intermediate products and increase the reactive surface area [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. A comparison of the yield and concentration of ethanol of all fermentation processes is presented in Table 3.…”

“…Palm date is very rich in sucrose, fructose and glucose. Other simple sugars (oses) were identified in some date varieties; it is arabinose, xylose, galactose and mannose present at very low concentrations [12]. Palm date can therefore be good candidates for the production of bioenergy.…”

“…Palm date can therefore be good candidates for the production of bioenergy. In Algeria, one of the leading countries in the production and export of dates in the world, palm date cultivars are numerous and poorly exploited, with the exception of Deglat-Nour, Ghars, Deglat-Beida and Mech-Deglat, which are of major economic importance [12]. Thousands of tons of dates remain unused and can exceed 50% of year-round production, which could be valorized [13,14].…”

Ovicidal Activity and Phytochemical Analysis of some Spontaneous Plants Extracts Against Ectomyelois ceratoniae (Zeller) Lepidoptera: Pyralidae

“…The cultivation of the date palm like all plants is confronted with several phytosanitary problems, such as Fusarium oxysporumf.sp albedinis diseases and pests such as the yellow mite Oligonychus afrasiaticus, the white scale Parlatoria blanchardi and the carob moth Ectomyelois ceratoniae. This last is currently considered as the most formidable predator of dates and as the main constraint to exploitation [3], it causes considerable damage to the crop both which decrease the yield product and the quality of the fruit, and also affects the fruits storage [4]. To overcome this issue, various control methods intensely developed to reduce the rate of infestations of this pest such as chemical treatment [5].…”

A new isolate ofNosema fumiferanae(Microsporidia: Nosematidae) from the date mothApomyelois(Ectomyelois)ceratoniae, Zeller, 1839 (Lepidoptera: Pyralidae)

“…This cosmopolite polyphagous pest causes significant damage to various crops throughout the world, which varies by region, host plant and plant variety. For instance, while it causes infestation on the date palm ( Phoenix dactylifera L.) in Tunisia and Algeria, it is a major pest of the pomegranate ( Punica granatum L.) in Iran and Turkey (Norouzi et al ., 2008; Idder et al ., 2009; Öztürk and Ulusoy, 2009; Zouba et al ., 2009; Öztop et al ., 2010). Besides these crops, there are lots of records of its damage on other host plants such as pistachio, Pistacia vera L. (Dhouibi, 1982; Mehrnejad, 1993), carob, Ceratonia siliqua (Gothilf, 1964), almond, Prunus dulcis (Mill.)…”
